Answer:

i) 302720

ii) 390909.09

Step-by-step explanation:

So to that end, here's the formula:

future \: value = (present \: value){(1 - rate)}^{time}

In part i, we do the following:

344000 {(1 - .12)}^{1}  = 302720

In part ii, we do the following:

344000 {(1 - .12)}^{ - 1}  = 390909.09

a white-tailed deer can sprint at speeds up to 30 miles per hour. American bison can run at speeds up to 3,520 per minute. Which
guajiro [1.7K]
For the answer to the question above,
In 1 minute, bison runs 3520 feet
In 60 minutes, the bison would run
3520*60 feet
211200 feet per hour.
These are equivalent to;
40 miles per hour since 1 mile is equivalent to 5280 feet.
The bison is faster by 10 miles per hour
Then If you convert the bison's speed to mph you get that it can run at speeds up to 40 mph.

I got this by seeing how many feet that they run in one hour so 3520 x 60 is 211200 which divided by 5280 is 40 mph.

I hope my answer helped.

John buys a computer with a 20% discount. If he paid $760 for the computer, how much was the discount?
Mumz [18]
If there was 20% taken off you add 20% back on and that is how you will get your answer. So take 760 plus the 20% which gives you 912 dollars
